The Planetary Health Expand initiative is working to drive global awareness and education within the global health and development communities about the impacts of the Earth crisis on every dimension of human health and all life on Earth, and why these communities are uniquely positioned to take action to address these challenges. The Expand initiative strives to ensure that clinicians, development experts, public health practitioners, and medical, nursing and public health students across the world expand their understanding of the urgency of the moment we face and how they can improve the quality of care and services provided while advocating for a just and livable future.

Planetary Health is a solutions-oriented, transdisciplinary field and social movement focused on analyzing and addressing the impacts of human disruptions to Earth’s natural systems on human health and all life on Earth. Uniting the efforts of the health and development communities to address global challenges such as climate change, biodiversity loss, food systems, pollution, and social justice issues will generate a stronger collective commitment to taking action on the Earth crisis, while also addressing some of the most significant threats to human health and well-being in the 21st century.
